Watch the world’s largest telescope, built to detect alien existence

About 10,000 people in China will be relocated to make way for the world’s largest radio telescope, which is built to detect alien existence. Built in the south-western Guizhou province, the 1.2 billion yuan (£128 million) project is part of the country’s ambitious hunt for aliens. To do that effectively, state-run Xinhua news agency reported that officials will “evacuate” all homes within three miles (5km) of the radio telescope.
